Should be possible, but i'm not really experienced as BS to be honest. Start with Weapon storm @ lvl 1 and kill some spiders, then i'd get a corrupted tower for the lane, helps you last hitting & keeps you save while you ran around merging stuff. I think it's best to go for an atack damage build in solo, so try to get divine sword, maybe sacred edge sword, probably the hunt item, bone axe (to farm)

In the early game try crafting grimmoire of the orc soul, or fashion armor or upgrade figurine; depending on the drops you get.

for killing death in solo . you need 3 impale armore + absolute ( or suprem if you know how to get it ) for kill the dragons you need dragon slayer wich is too hard to get if you couldnt get dragon slayer. kill dragon with goldensword + scared A.ring .

If you know the recipes get celestial sword, vampiric sword, Figurine of magnificence, For crit get either Sacred Edge Sword, the upgraded Masamune or Mugen/Slicer. You need an atack type change item, if you can get it get dragon slayer, if not get excalibur. Get supreme as defensive item.

If you wanna go retaliation build just get 2/3 impale armors and other good defensive items (Adamantium Armor, Eagle, Supreme ), and maybe an arcane szepter to do more damage with retaliation.
